NVH Vibration Testing
ยต-REMUS is a universal software toolbox for nearly all kinds of NVH (noise, vibration, harshness) applications, e.g. signal and modal analysis, order tracking, machine diagnostics, balancing, human vibrations, noise analysis.
Signal Analysis
|
|
By means of the ยต-REMUS - Signal Analysis program module different types of vibration signal processing can be performed. Time series, FFT spectra, auto- and cross-spectra, transfer and coherence functions can be recorded.
|
Order Analysis
|
|
By means of the ยต-REMUS - Order Analysis program module acceleration and deceleration runs of rotating machinery may be recorded and analysed. While the test is still running, time series, magnitude spectrum, 3D-waterfall and Campbell diagrams of the order domain spectra can be displayed online. In addition, during offline analysis, order tracking can be performed and frequency (FFT) domain spectra can be displayed (3D-waterfall and Campbell).
|
Modal Analysis
|
|
The ยต-REMUS - Modal Analysis program module is used for structural analysis of a mechanical system. The geometrical structure of the testing object is defined by the input of test-point coordinates as well as connecting lines and surfaces. Initially, the recorded signals are evaluated by means of the ยต-REMUS - Signal Analyzer. Once the modal parameters (frequencies, decay factors, eigenvalues) have been determined, animated displays for each mode as well as for every single spectral line of the transfer functions are available.

Human Vibrations
|
|
All manufacturers of machinery and vehicles are obliged to verify the conformity of their products with EU regulations concerning the impact of mechanical vibrations to the human body. ยต-REMUS includes a specific analysis module for this purpose.
|
Balancing
|
|
An existing imbalance may cause undesirable or intolerable vibrations in mechanical structures. By means of the ยต-REMUS - Rigid Body Balancing program module this imbalance can first be examined and then be eliminated thus providing an adequately smooth running behavior.
|
Acoustical Camera
|
|
The acoustical camera makes noise visible. So it is possible to localize specific noise sources in complexe structures and analyze their frequency spectrum.
|
Noise Analysis
|
|
Any working machinery causes noise which may be undesirable or intolerable. By means of the ยต-REMUS - Sound Intensity program module the occurring sound emission can be analyzed. A robot control may be used to enable automatic scanning of the predefined sound field.
|
NVH Sensors
|
|
The selection of suitable sensors, e.g. microphones, accelerometers, Modal hammers etc., is essential for the quality of NVH analysis. Please ask our application specialists for competent advice.
